Instructions
Give your eel live food, if possible, especially when it first arrives to live in your aquarium. Depending on your eel, some of the creatures it might like to eat include live feeder fish, small crustaceans, bloodworms or grass shrimp.
Space out your feedings. Most eels only need to be fed twice or three times a week. Some will only feed once every two to three weeks..
Teach your eel to eat from a feeding stick. Because it is not always practical or possible to have live bait on hand, eels should be trained to eat dead creatures. Use a hard stick that is long enough to reach down to where your eel lives and thick enough to withstand the bite of your eel, especially if you are feeding a strong-jawed moray. Place a dead creature, such as a gulf shrimp -- depending on your eel type -- onto the end of the stick and bump the eel gently with the food until it takes it.
Drop frozen food such as shrimp or worms into the tank. Once your eel becomes accustomed to eating dead creatures, it won't need to be fed with a stick.
Feed your eel at night just before you turn off the lights. Most eels are nocturnal animals and are usually most comfortable feeding at night.
Schedule your feedings to suit your eel. Once you have gotten to know your eel, you will know approximately how often to feed it. Keep an eye on your smaller fish and if they look as if they have been nibbled on, it is possible the eel is hungry and trying to snack on them. If that is the case, feed the eel more often.
Use a turkey baster to squirt live blackworms into your aquarium's substrate where they can burrow until your eel finds them. This is a good way to feed freshwater eels.
How to Feed Live Eels
Eels or eel-like fishes are popular and interesting additions to both saltwater and freshwater aquariums. True freshwater eels belong to the order of fish known as anguilliformes, but there are also long, snake-like freshwater fish that are also called eels. While morays are probably the most commonly recognized saltwater eel, there are also other types, including wolf and snake eels. To thrive in an aquarium setting, eels need places to hide and to be properly fed.
